2 Datagrid columns questions

[Mark B]

I have a Datagrid working fine, outputting:

Group
Most Popular Product Code
--------
-------------------------------

Earth.New Zealand
32
Earth.New Zealand
32
Earth.New Zealand.Auckland
32
Earth.New Zealand.Auckland
32
Earth.New Zealand.Auckland.Auckland
7
Earth.New Zealand.Auckland.Auckland.Parnell
7
Earth.New Zealand.Auckland.Henderson
10024
Earth.New Zealand.Auckland.Henderson.New Account
10024
Earth.United States
32
Earth.United States.Texas
32


Now I want to do these 2 things:

1) Have clickable hyperlinks on each sub-group and not the periods e.g. for
the last entry above (Earth.United States.Texas):

<a href="http://www.mysite.com/showgroups/?GroupName=Earth">Earth</a>.<a
href="http://www.mysite.com/showgroups/?GroupName=Earth.United
States">United States</a>.<a
href="http://www.mysite.com/showgroups/?GroupName=Earth.United
States.Texas">Texas</a>

I still want people to be able to sort the column as displayed though.


2) Rather than display the Most Popular Product Code (SQL int), I want the
result of the function fConvertCodeToProductTitle(lngProductID as Long) as
String. I still want people to be able to sort by the long integer value
though -- even though I don't want it displayed for the column.

How can I do this with the Datagrid control (Visual Web Developer 2008
Express)?

TIA

Hi

on item data bound change your output as you want...

Hi Mark,

For your scenario, since the string transforming logic is not that
simple(you need to format both the display string and the url string ), I
think you'd better write a helper function in codebehind and call this
function to perform transform in your databinding control.

Here is a test function I've written which accept an input string and
transform it to output html hyperlinks:

===========================
protected void Page_Load(object sender, EventArgs e)
{
string ret =parse_string("Earth.New Zealand.Auckland.Henderson.New
Account");

Response.Write("<br/>" + ret);
}

string parse_string(string input)
{
const string stmp = "<a
href='http://www.mysite.com/showgroups/?GroupName={1}'>{0}</a>";


string[] items1 = input.Split('.');
string[] items2 = new string[items1.Length];

for (int i = 0; i < items1.Length; ++i)
{
items2 =string.Join(".", items1, 0, i + 1);
}


StringBuilder sb = new StringBuilder();
sb.AppendFormat(stmp, items1[0], items2[0]);

for (int i = 1; i < items1.Length; ++i)
{
sb.Append("."); sb.AppendFormat(stmp, items1, items2);
}
return sb.ToString();

}
=========================

You can call this funcction in your databinding control to format the
certain data field (string value).

Hope this helps.

Sincerely,

Steven Cheng
